Corrosion Inhibitors

ENJ Projects Nigeria Limited Supplies high quality range of paints and Coatings, floor coatings, coatings are generally packaged in two parts that are mixed prior to application.

• Floor coatings is our specialty
• Chemistry of Paints and floor Coatings

The two parts consist of 1) Resin that is cross-linked with 2) a co-reactant or hardener. Epoxy paints and coatings are formulated based upon the performance requirements for the end product. When properly catalyzed and applied, epoxies produce a hard, chemical and solvent resistant finish. They are typically used on concrete and steel to give resistance to water, alkali and acids. It is the specific selection and combination of the epoxy component and the hardener component that determines the final characteristics and suitability of the epoxy coating for a given environment.

Substrate Types:

• Steel, Concrete, etc. Is it suitable for the coating and the environmental exposure?
• Surface Prep

Are the requirements adequate?

• Temperature/Variations
  Normally above 55ºF for the first 72 hours of drying, and at least 5ºF above the dew point.
• Humidity
  Normally below 85% required.
• Environmental Exposure
  Is the coating suitable for the conditions it will be exposed to?
• Performance Requirements
  What performance characteristics will the coating be exposed to? (i.e. abrasion, flexibility, heat resistance, etc.)
• Re-coatability
  Will it be required and within what time frame?
• Application Methods of Epoxy Paints and epoxy floor Coatings
  Is the coating designed for the specific method? (i.e. spray, brush, roll, squeegee/trowel)
• Cost/Value Considerations
  Cost per mil per square foot per year of life expectancy.
• Film Build
  Is the coating able to comply with the specifications?
• Air
  Movement It is very important to have fresh air circulating over the surface during drying.
• Induction Time
  Critical, especially during cold weather and high humidity.
• Pot Life
  Do not exceed. Coating may appear usable but will exhibit poor performance.
• Aesthetics
  Be aware that some epoxies yellow more than others. More noticeable in whites and off-whites.
• Odor
  Will odor be a concern in or around the application area? Solvent based, water-based, high solids epoxies.
• Literature Of Epoxy paints and Coatings

Paints and coatings are used because they offer outstanding chemical and water resistance, are extremely durable and have excellent adhesion to a variety of substrates. They are two-pack paints which mean they consist of two components (a base and a curing agent) which must be mixed together in the right ratios prior to application.
The addition of solvents (also known as thinners) to epoxy products is not strictly necessary however in certain conditions can aid application. Extra solvents will allow the product to flow out better, and will aid penetration into substrates such as wood and concrete.
